Paper Abstract

This paper describes an acousto-optic signal processor that generates and controls the set of time delays required for RF antenna array true time delay beamsteering. The time delay controller can scan an RF array beam rapidly over a continuum of angles with a tone whose frequency determines the pointing angle of the RF array beam. The time-delay controller also provides the proper relative phases between the carriers of the time delayed signals at the RF of the antenna array. A proof-of-principle breadboard of the time delay controller was assembled. Results of the demonstration of the breadboard are presented.
